Abstract

A mobile communications system is disclosed that includes a first local routing manager (LRM) providing a first network in which a mobile terminal is currently located, a second local routing manager (LRM) providing a second network in which a counterpart terminal communicating with the mobile terminal is currently located, and a home routing manager (HRM) managing correspondence between the unique home address of the counterpart terminal and the second network. The first LRM has a controller that acquires address information of the counterpart terminal from the second LRM, via the HRM, when the first LRM does not have the address information, and communication means that transmits the address information of the counterpart terminal to a router of a new cell in the first network when the mobile terminal moves into the new cell.
